Characteristic：
Low oxygen content, fine particle size, and good compression performance.
Application：
1.Metal nano lubricant additive: Add 0.1-1% nano tin powder to lubricating oil and grease to form a self-lubricating and self-healing film on the surface of the friction pair during the friction process, reducing the anti-wear and friction reducing performance of the friction pair.
2.Activated sintering additive: Nano tin powder reduces the sintering temperature of powder metallurgy products and high-temperature ceramic products in powder metallurgy.
3.Surface conductive coating treatment for metals and non metals: Coating is carried out under oxygen free conditions at temperatures below the melting point of the powder, and this technology can be used for the production of microelectronic devices.
4.Brazing and soldering industry: used to prepare high-performance welding and packaging alloy materials, used to improve welding performance and reduce welding temperature. Tin powder is the main raw material for producing solder paste, with uniform particle size and suitable for the soldering industry. It has good fluidity and fine powder particles, which can improve the fineness of solder paste.
5.Tin powder is widely used in the manufacturing of electronic products in the electronics industry. It can not only serve as a solder to connect electronic components together, but also as a coating material to protect electronic components from oxidation and corrosion. Tin powder can also be used to manufacture conductive adhesives, replacing wires to connect electronic components.
6.In the chemical industry, tin powder is used to manufacture various chemical products such as tin sulfate, sodium stannate, potassium stannate, etc. These compounds have wide applications in fields such as pesticides, ceramics, printing and dyeing.
7.In the mechanical manufacturing industry, tin powder is used to manufacture various mechanical components such as bearing seats, gears, as well as screw tin mother powder. It is also used to manufacture wear-resistant materials and improve the wear resistance of mechanical components.
8.In the construction industry, tin powder can be used to manufacture various building products such as tiles, flooring, etc. Tin powder can also be used for decoration of buildings.
9.Used in fields such as powder metallurgy, electric carbon products, diamond tool products, electronic materials, friction materials, oil containing bearings, spraying materials, welding materials, pharmaceutical and chemical industries, metallurgical analysis fluxes, etc.
